Abstract

The invention discloses a salt spray testing machine, and belongs to the field of salt spray tests. The salt spray testing machine comprises: a detachable box cover arranged above a box body, whereina discharge port is formed in the side wall of an objective table, and a box door is arranged on the discharge port; a workbench which is horizontally and fixedly mounted in the box body, an opening is formed in the upper portion of the workbench, and the workbench, the box cover and the box body form a working cavity; an inner cavity which is arranged below the workbench, wherein the inner cavityis communicated with the workbench through the opening, and the inner cavity is communicated with the workbench through the discharge port; a salt mist spraying system which is mounted on the workbench; the objective table which is arranged above the inner cavity; an air inlet channel, wherein one end of the air inlet channel extends out of the box body and is provided with an air blower, and theother end of the air inlet channel is communicated with the inner cavity; and an air outlet channel, wherein one end of the air outlet channel is extended out of the box body. Compared with the priorart, the salt spray testing machine has the advantages that salt spray can be discharged after testing, and operators are prevented from making contact with the salt spray.

Description

technical field [0001] The invention relates to the field of salt spray testing, in particular to a salt spray testing machine. Background technique [0002] Salt spray corrosion is a common and most destructive atmospheric corrosion. Among them, the chloride in the atmosphere has the most obvious corrosion effect on metals. Its main corrosion component is the chloride salt in the ocean—sodium chloride, which mainly comes from the ocean and inland saline-alkali areas. The corrosion of salt spray on the surface of metal materials is caused by the electrochemical reaction between the contained chloride ions penetrating the oxide layer and protective layer of the metal surface and the internal metal. At the same time, chloride ions contain a certain amount of hydration energy, and are easily displaced by the pores and cracks adsorbed on the metal surface to replace the oxygen in the oxide layer, turning insoluble oxides into soluble chlorides, and turning the passivated surfac...
